For oils, clears, enamels. Use to paint very small areas and molding and furniture. For super smooth, smooth and semi-smooth surfaces. For doors, molding, trim and cabinets. Doesnt leave unsightly fuzz, lint or seam marks. Foam conforms to surface irregularities and provides contour coverage. Will not "mat down". Has a "reservoir action" and carries most of the paint below the surface in thousands of tiny open cells. Less frequent "dipping" and less "spreading out" of paint. Cleans quickly and easily.
